The purpose of the paper was to study the problem of confidence estimation of basic reliability indicators, such as the system failure-free operation probability for a given time and guaranteed uptime, with a given guarantee level, for a system model with arbitrary redundancy modes, loaded or unloaded, in various subsystems. When studying the problem, we relied on the elements test results. Problems like that are often found in engineering practice when designing and experimentally developing modern complex engineering systems and their various components. The paper gives the construction of lower confidence limits for the indicated main indicators of the system reliability based on the available statistical information on the test results of its elements, and also presents  approximate asymptotic (for the case of high reliability) expressions obtained for the lower confidence limit of the system reliability function
